Specification of Letters Patent.

Application filed August 27, 1907.

Patented March 17, 1908.

Serial No. 390,275.

To all whom t may concern: i YBe it known thatI, RICKLEF FoLxnnTs,citizen of the United States, residing at Lakeiield7 in the county ofJackson and State of Minnesota, have invented certain new and usefulImprovements in Scrapers, of which the following is a specification.

This invention relates to cultivators of the disk type, and moreparticularly to attachments therefor, and has for its object to providea scraping attachment for disk cultivators which will be arranged toefficiently remove earth adhering to the disks and which will bearranged to automatically compensate for wear.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,

Figure 1 is a top plan of a cultivator provided with the presentinvention g F ig. 2 is a side elevation.

Referring now to the drawings, there is shown a cultivator includingrearward axles 5 and 5 upon which there are mounted a pair of rearwardlydivergent disks, 6. A pair of uprights 7 are mounted upon the axlesbetween the disks and have their upper portions turned laterally andgiven a quarter twist to bring them into vertical planes, as shown at S,and these portions 8 have their outer edges cut away to form upper andlower spaced 'fingers 9, each of which is given a turn to bring it intoa horizontal plane.

Scraper arms 10 are provided, each having their opposite edge portionscut away as shown at 11, adjacent to one end, to form a reduced neck 12,which is engaged between the fingers 9 of one of the uprights 7, a pivotpin 13 being engaged through the reduced neck and the fingers.

The scraper arms extend forwardly beyond the uprights, as shown at 14,and rearwardly of the uprights, the scraper arms are extended downwardlyand outwardly over the outer or convex faces of the disks, where theyare provided with scraping blades 15 which engage the convex faces ofthe disks.

It will be observed that the scraper arms are pivotally mounted so thatthe blades 15 may be moved into and out of engagement with the disks,and to hold the arms yieldably in engagement with the disks, a spring 16is engaged between the forward portions of the arms and has its en dssecured in openings 17 formed in the arms.

It is thought that the action of the scraper will be clearly understoodwithout more definite description.

Vhat is claimed is:

The combination with an agricultural implement including spaced disksand axles therefor,. of supports carried by said axles and locatedbetween the disks, an arm pivoted to each support, said arms extendingforwardly beyond the supports and extending rearwardly and downwardlyover the convex faces of the disks, scraper blades carried by therearward ends of the arms, said scraper blades extending transversely ofthe disks, and a spring engaged between the forward ends of the arms andarranged to lhold the arms with their transversely extending bladesyieldably in engagement with the disks.

In testimony whereof I affix my signature, in presence of two witnesses.
